COMBINATION FLASH-LIGHT AND CIRCUIT TESTER.

, Application led Junel29,

My invention belongs to that general class of devices known vas Hashlamps or lights and relates more particularly to a combined flash lightand tester, which fis convenient for use by electricians, mechanics,motorists andthe like, for testing fuse plugs, electric light wiring,ignition wiring and generally as a trouble shooter, as well as a simpleandL convenient trouble light or the like for the 10, purposes for whichflash lights are generally characters indicate like or correspondingparts,

Fig. 1 proved device; f

Fig. 2 is a view of one of the contacts, showing a no-vel form ofprotecting cap;

Fig. 3 isa similar view showing another type of cap; and

Fig. '4; is a similar view illustrating another type of protecting cap.Referring to` the drawings, in which the preferred embodiment of theinvention is shown, I have illustrated a Hash lamp similar to those ingeneral use, it being understood that the details of the lampconstruction and battery container may be modified without departingfromthe general construction of. my improvement. l v f y s shown, 1represents a casing of suitable material such4 as metal, provided withan end cap 2 which is preferably removable and with a threaded flange 3arranged to receive a lens retainer 4. Arranged within the casing is thebattery 5 consisting of one or more cells, depending upon the size anddesign of the casing, which need not necessarily be cylindrical asshown. The particu-v lar casing 1 shown is of metal and may therefore beused -as one of the conductors or contacts, the same being electricallycon- Cal is a sectional view through my i111.-

nected with the battery by the spring 6, which also maintains thebattery against displacement and against one of the terminals of thelamp. The opposite end of the battery is 'provided with the usualterminal 7 G0 arranged to contact with the terminal 9'on the lamp 8, theshell 10 on the lamp .also serving as a conductor, it being understoodthat the terminals 9 and 1() are connected with the lamp filament, Thelamp as shown G5 l is arranged to be carried by the reflector member 11,which may be insulated from the casing by the insulating member 15. Ihave shown a lens v12'secured in place by the y retalner 4, the lensalso serving to secure the reflector in place. There is provided a`switch member 14 arranged to be controlled from the exterior of thecasing by vthe button or slide 13.

When the slide` is moved up member 14 contacts with the 75 reflectorwhich is in electrical contact with the shelh 10, thereby closing thecircuit and causing the lamp to be lighted, thereby indicating that thebattery is alive,

as well as permitting the lamp to be used for 50 lighting purposes.

There. is in addition provided one or more terminals which are normallya part of an open circuit against which a device to bey tested maybeplaced, closing the circuit and -causing the lamp to be lighted, therebyindicating a closed circuit through the device to be tested. In theparticular device illus- K trated, the'casing being o-f metal, it isnecessary to provide only one Contact, the metallic casing itselfserving as acontact and obnductor. As shown, I have provided a contactmember 17 which is suitably insulated from the casing, but which isprovided with a stem 18 extending to the interior of the/cas- 05 ingvand which carries a spr-ing or contact member 19 arranged to contactwith the rel'ector shell or the shell 10 on the lamp. The particularcontact shown is insulated from the casing 1 and washer 20by insulation21. 100 J In order to prevent the accidental short- .circuiting of theterminal 17 withthe casing,

as for example when the lamp is in -a tool box or the like, I have shownin Fig. 2 how a rubber cap 25 may be positioned over the 105 same exceptduring such time as the lamp is used for testing purposes. If desired,the part 2O may be slightly reduced, as indicated at 26, so that therubber cap is firmly held in place. A piece of rubber tubing may 1.10

be provided for the same purpose if desired. In Fig. 3 I haveillustrated a metal or fiber cap 27 which may be internally screwthreaded and arranged to 'engage a thread on 20 corresponding to 20. InFig. 4; I have illustrated how a sliding cap 28 might be arranged on thedevice for the same purpose.

From the preceding it Will be obvious that I have provided a tiash lampwhich may be used in the ordinary manner for the usual purposes, butwhich may also be used for testing purposes Without in any Way affectingits use as a lamp. I'have also provided a construction that does notinvolve a radical departure l'rom the present well known types vhence Ido ndt Wish to be understood as limiting myself t`o the exact form,construction,

arrangement and combination of parts herein shown and described, or usesmentioned.

What I claim as new and desire to secure by Letters Patent is:

The combination with a flash light having a control switch, a metalliccasing, a metallic reflector insulated from the casing and adapted toengage a terminal of the lamp, of a contact member having 'a stemprojecting through the casing, a washer on the stem tapering inwardlytoward the casing, insulation between the stem and Washer and betweenthe cont-act and Washer, resilient means at the inner end of the stemengageahle with the retlector to form a circuit with the lamp fortesting purposes, and au insulating shield fitted over thc contactmember with its inner portion contracting over the tapering portion ofthe washer to prevent accidental displacement of said shield;

In testimony lwhereof, I have hereunto signed my name.
